N 0. 836,207. Specification of Letters Patent. Patented N 0v. 20, 1906.

Application filed November 11,1905. Serial No. 286,966.

To all whom it may concern:

Be it known that I, LEON L. Pack, a citizen of the United States, residing at Canisteo, in the county of Steuben and State of New York, have invented certain new and useful Improvements in Fire-Extinguishing Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled inthe art to which it appertains to make and use the same.

My invention relates to automatic chemical fire-extinguishers, and its object is to provide an apparatus of this character having means whereby a chemical compound can be discharged at any point where the temperature is raised above a predetermined degree.

The invention consists of a tank of an ordinary chemical fire-extinguisher type, which is normally held in an upright position. by a supporting device which extends into close proximity to a series of nozzles connected to a distributing-pipe, which in turn communicates with the tank through a flexible pipe. Each nozzle has a destructibleclosure adapted to be removed automatically when subjected to a predetermined degree of heat, said removal causing the breaking of the supporting device, whereby the tank of chemicals will drop into an inverted position and the chemical compound be discharged into the distributing-pipe and expelled through the uncovered nozzle.

The invention also consists of the further novel features of construction and combination of parts, the preferred forms whereof will be hereinafter more particularly set forth, and pointed out in the claims.

In the accompanying drawings I have shown the preferred forms of my invention.

In said drawings, Figure 1 is an elevation of my improved fire-extinguishing apparatus. Fig. 2 is an enlarged section through one of the nozzles and its closure, and Fig. 3 is an elevation showing a modified means for mounting the tank.

Referring to the figures by numerals of reference, 1 is a tank containing any suitable fire-extinguishing chemical and pivotally mounted upon a bail'Z, which is supported on a hook 3 or otherwise mounted. A flexible ipe 1 extends from the upper end of the tanl to a distributing-pipe 5, and arranged at are nozzles, each of which consists of a frustoconical head 6, in which is mounted a perforated disk 7. Below this disk and within the head 6 is disposed a closure 8, formed of any suitable material, such as can be readily broken by concussion, and extending from this closure is an explosive cap 9, adapted to be exploded whenthe temperature reaches a predetermined degree. Extending through or under the caps of all the nozzles is a cord or wire 10, said cord being supported at desired intervals by eyes 11. Two of these eyes are disposed at opposite sides of the hook 3, so that the cord can extend downward from them through the eyes 12 upon the top of the tank 1, and thereby support the tank in a substantially upright position, although the same is inclined slightly to one side of its center of gravity.

It is thought that the operation. of the apparatus will be obvious from the foregoing description. IVhen heat of an unusual degree is generated adjacent any one or more of the nozzles, the caps of said nozzles will be exploded and shatter the closures 8, so that the lower ends of the nozzles will be free of all obstructions. At the same time the cord 10 will be broken and the upper end of the tank 1, being thus relieved of its holding means, will swing downward, so that the tank will assume an inverted position and cause the generation therein of the extinguishing mixture, which will in turn be discharged through the pipe 4 into the distributing-pipe, and from said pipe through the opened nozzles.

Although I preferably construct the apparatus in the manner shown in Fig. 1, the tank may, if desired, be held in a perfectly upright position, as shown in Fig. 3. it will be noted that the. cord 13 extends from the tank around a pulley 14 and serves to hold the tank firmly against a spring 15, projecting from a bracket 16. When the tank is upright, the. spring is compressed; but as soon as the cord is severed the spring will expand and throw the tank off center, so that the same will swing downward into an inverted osition. v

Havlng thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In an apparatus of the character described, the combination with a distributingsuitable intervals upon this distributing-pipe pipe having a nozzle thereon and a closure In this figure for the nozzle adapted to be automatically removed when exposed to a predetermined degree of temperature; of a pivotally-mounted fire-extinguisher-containing tank, a flexible device normally supporting the tank out of operative position, said device extending in close proximity to the nozzle and adapted to be severed by the opening of said nozzle to release the tank, and a tubular connection between the tank and a distributing-pipe.

2. In an apparatus of the character de scribed, the combination with a pivotallysupported tank and a flexible device for holding said tank with its top uppermost; of a distributing-pipe and a flexible tubular connection between the pipe and the tank, a nozzle extending from the distributing-pipe and a closure for the nozzle adapted to be destroyed when subjected to a predetermined temperature, said flexible supporting device, adapted to be simultaneously severed with the destruction of the closure.

3. In a fire-extinguishing apparatus, the combination with a chemical-containing tank pivotally supported and a flexible device for normally holding the tank with its top uppermost; of a distributing-pipe flexibly connected to the tank, a plurality of nozzles extending from said pipe, closures for the nozzles adapted to be destroyed when subjected to predetermined temperatures,

said closures being engaged by and adapted to sever the flexible tank-supporting device.

4. In a fire-extinguishing apparatus, the combination with a distributing-pipe having a nozzle extending therefrom and a closure for the nozzle adapted to be automatically removed when subjected to a predetermined temperature; of a pivotally-sup orted tank, a flexible tubular connection etween the tank and the distributing-pipe, and means Ior normally holding the tank top uppermost, said means adapted to be severed by the removal of the nozzle-closure.

5. In a fire-extinguishing apparatus, the combination with a distributing-pipe having a nozzle extending therefrom, a destructible closure within the nozzle and an explosive cap within the closure and adapted to be exploded at a predetermined temperature; of a pivotally-supported tank, a tubular connection between the tank and distributing pipe, and means for holding the tank normally with its top uppermost and adapted to be released by the explosion of the cap.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
